I was chatting with some friends recently about monster movies and creature features as they have been a mainstay of cinema for as long as the medium has existed. At it’s best, a good cinematic monster or monsters are a metaphor for examining a societal ill or it can also be a clever MacGuffin to explore the human condition. Clive Barker’s troubled film, Nightbreed being a prime example of this where the monsters are the persecuted protagonists and the humans are terrible creatures, lacking empathy. However, be your narrative deep or simple, if you’re going to have a monster in your film, then try to do it right. A poorly realised design or badly implemented, low budget visual effects can work against the credibility of your creature and there are no shortage of cinematic examples. So I thought it would be fun to list a few “bad” movie monsters. I try to provide some context with each example as to why each particular monster didn’t quite work. Naturally I have not in anyway created a definitive list and would be happy for readers' comments if they have other examples they’d care to share.
